Abstract
Techniques for alternating current (AC) powering methods deployed at a power transmitter and a power receiver for line fault detection. AC power is applied to a pair of lines at a power transmitter to transmit the AC power to a power receiver. An occurrence of a predetermined characteristic of an AC voltage waveform or an AC current waveform is detected. The AC power is disconnected from the pair of lines upon detecting occurrence of the predetermined characteristic. Fault detection is performed during a safety check time window upon disconnecting the AC power from the pair of lines. The AC power is reconnected to the pair of lines when a fault is not detected from the fault detection during the safety check time window, and the AC power is maintained disconnected from the pair of lines when a fault is detected during the safety check time window.
